Description

The SCS-320-GR (Solar Charging Sight) is designed for P320 optics ready handguns or other DPP footprint applications. It is designed to attach directly to the slide without an adapter plate and uses our innovative solar charging system with multi-directional light sensors to automatically adjust brightness in dynamic situations. The SCS can potentially operate indefinitely using an internal, rechargeable 20,000-hour battery meaning under even moderate exposure to bright light, you will never need to change batteries again. The SCS also includes an intensity override function which locks the optic into a high brightness mode for 30 minutes and a low power indicator which warns of low battery days before charging is needed.

  • A+ Just buy it!!!
Color: Coyote Tan
Now that I have had this optic and used on the range a bunch of times all I can say is do yourself a favor and buy it! You won't regret it. I have it on the latest model of the Sig Sauer M17 (P320). And it stays sighted in after you do so. The different brightness levels you can adjust are perfect. I have had to adjust for outdoor and indoor ranges and works perfectly. Battery life, for me doesn't matter and will never loose its charge cause I shoot a lot outside and that solar recharge panel works beautifully. Highly recommend and it also looks bad ass! ... show more

  • Perfect fit for my p320c
Color: Black
I have owned multiple Red Dot from this brand, and I have never been disappointed. The brightness is fantastic and is very easy to install. I expect the same battery life from this one since it is also powered by the sun, which helps prolong your battery life.

  • True to their word
Color: Black
Was looking for an optic for my p320. Stumbled on a review for this optic and liked what they said. Stalked about 6 more reviews and was still sold on it (hoping it was as good as they said) it was! So far . Put it on in less than 5 minutes. The circle looked like a burst and figured I'd have to where my glasses for crisp lines. I was wrong! at 6 yards, 11 yards, 25 yards I could see the lines with very little burst! I didn't need my prescription glasses on to make the view crisp , almost no burst (like on a different Holosun on. Took to the range, spot on!! No adjustments needed!(for me) Just 100 rounds Let's see over time and use to see how it holds up but as for now definitely a believer!! ... show more

  • Best red [green] dot sight for your p320
Color: Coyote Tan
Absolutely perfect fit on the p320 m18. Crystal clear with choice of dot, circle or both. No blume on the dot. Love it! And it's $50 cheaper than a delt point pro (another great pistol redot)

  • Great, but should have shake awake
Color: Black
Not having shake awake took this from 5 to 4. I missed that it didn't. Great looking, great brightness. High quality glass. You can't really get a better optic in my opinion. You're obviously paying for that quality, because it's not a cheap optic. So mid value for money. Easy to adjust and a forgiving sight window. Easy to use and change sights ... show more
